disc. Posterior margins of disc mildly convex. Anterior margins almost straight.
Eyes small and widely spaced. Tail less than 2 times body length with broad, long ventral
tailfold. At midpoint, tailfold around is between 3.6 to 5.7 times as high as tail. Tailfold does not reach tip when
filament intact. Tail/tailfold beyond tailfold origin is dusky. Short row of
enlarged heart shaped mid-scapular denticles behind eyes.
Marine and estuarine environments. Sandy
sea grass beds and areas adjacent to
reefs Max depth unknown.
Pacific. Madagascar to Southeast Asia and Western Australia.
Listed as Data
Deficient by the IUCN. Cowtail Stingrays (Pastinachus) are reported
throughout the Indian Ocean to the western Pacific,
but there is a complex of species. They are captured in demersal tangle net, bottom
trawl, longline, Danish seine and beach seine fisheries in Southeast Asia and
parts of the Indian Ocean. Inshore fishing pressure is intense throughout large
areas of the species' ranges in Southeast Asia and in parts of the Indian Ocean.
They are caught in particularly high numbers in the target fishery for rhynchobatids operating in the Arafura Sea. Although no species-specific data
is available, overall catches of stingrays are reported to be declining, with
fishermen having to travel further and further to sustain catch levels. Given
continuing high levels of exploitation throughout their range in Southeast Asia
and evidence for declines in catches of stingrays, They are regionally assessed as
Vulnerable there. Fisheries in northern Australia are generally well managed and
the introduction of Turtle Exclusion Devices (TEDs) and other exclusion devices
will have greatly reduced bycatch of these species. They are considered at
minimal threat throughout their wide range off northern Australia, where
assessed as Least Concern. Globally, investigation is vital to resolve the
taxonomic issues associated with this species complex and it is not possible to
assess them beyond Data Deficient at present. Further work is required to identify
the species involved and make full assessments of their status.

is very difficult to distinguish from P.atrus. The
narrowtail stingray - Pastinachus gracilicaudus has circular
denticles and a narrower ventral skinfold on its tail.
Reaction to divers:
Fairly easy to approach but
bolts upon close inspection.
Present in many areas. I
have seen this ray on shallow reefs in the Arabian Sea off of Abu
